HPLC Guard Columns and Cartridges
MilliporeSigma™ Supelco™ Ascentis™ Express HILIC Guard Cartridge, 2 μm Particle Size
Ascentis™ Express Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of Ascentis™ Express columns.
MilliporeSigma™ Supelco™ Nucleosil™ Guard Column phase C18 (octadecyl), 5 μm Particle Size
Use guard cartridge holder 54987
MilliporeSigma™ Supelco™ Ascentis™ C18 Supelguard™ Guard Cartridge, 3 μm Particle Size
Ascentis™ C18 is an extremely stable and reliable HPLC column that gives symmetric peak shape and excellent retention even for difficult compounds.
MilliporeSigma™ Supelco™ Discovery™ BIO Wide Pore C5 Supelguard™ Cartridge, 5 μm Particle Size
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately. The 2.1 and 4 mm I.D. cartridges use 21150AST or 59660-U (both stand-alone) or 504254 or 55205 (both integral). The 10 mm I.D. cartridges use 567499-U. The 21.2 mm I.D. cartridges use 581392-U.

TSKgel™ SuperMPHZ-N Guard Column, 3 μm Particle Size, Sold by MilliporeSigma™ Supelco™
Tosoh′s innovative multi-pore technology is now also available in 3, 4 and 6 μm TSKgel™ SuperMultiporeHZ Columns and Guard Columns.
TSKgel™ SuperAW Guard Column, 7 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel Guard Columns are stand-alone and do not require separate holders. For use with TSKgel SuperAW2500-4000 Columns.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-ABZ Supelguard Cartridge Kit, 5 μm Particle Size
SUPELCOSIL™ LC-ABZ phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-CN Supelguard Cartridge, 5 μm Particle Size
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-ABZ Supelguard Cartridge, 5 μm Particle Size
SUPELCOSIL™ LC-ABZ phase has a unique deactivation technology which provides excellent reversed-phase performance for basic compounds, as well as those that are acidic, polar neutral, and non-polar.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-NH2 Supelguard Cartridge Kit, 5 μm Particle Size
SUPELCOSIL™ LC-NH2 Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits (2 μm porosity).
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-1 Supelguard Cartridge, 5 μm Particle Size
Due to a mixed retention mechanism, selectivity differences for polar groups are more pronounced than on C8 and C18 columns. C1 columns require 20-30% less organic modifier to provide retention similar to C18 columns.
TSKgel™ SuperAW Guard Column, 13 μm Particle Size, Sold by MilliporeSigma™ Supelco™
TSKgel Guard Columns are stand-alone and do not require separate holders. For use with TSKgel SuperAW5000-AWM-H Columns.
MilliporeSigma™ Supelco™ SUPELCOSIL™ LC-8 Supelguard Cartridge Kit, 5 μm Particle Size
Provides less retention of both polar and non-polar compounds than C18.
